Testing the social investment principle around childbirth: little evidence for personality maturation before and after becoming a parent

The Role of Personality, Just World Beliefs, and Rape Myth Acceptance on Sexual Violence Bystander Intentions

Socioecological models of bystander intervention suggest that a complex decision-making process is required for a prosocial bystander to intervene, starting with intrapersonal variables of cognition and personality. This study investigates how rape myth acceptance, personality, and just world beliefs impact the frequency of positive bystander intention. The study's sample size consisted of 139 college students. Participants completed an online survey in which they read a vignette and indicated whether they would intervene as a bystander at 25 different instances throughout the vignette. Correlational analyses showed that agreeableness and openness were positively associated with prosocial bystander behavioral intention. A multiple regression analysis found only the belief that the world was a safe and good place was predictive of prosocial bystander behavioral intention. The results suggest that bystander intervention education programs should be revised to address just world beliefs.

Longitudinal bidirectional associations between personality and becoming a leader

OBJECTIVE

Leaders differ in their personalities from non-leaders. However, when do these differences emerge? Are leaders "born to be leaders" or does their personality change in preparation for a leadership role and due to increasing leadership experience?

METHOD

Using data from the German Socio-Economic Panel Study, we examined personality differences between leaders (N = 2683 leaders, women: n = 967; 36.04%) and non-leaders (N = 33,663) as well as personality changes before and after becoming a leader.

RESULTS

Already in the years before starting a leadership position, leaders-to-be were more extraverted, open, emotionally stable, conscientious, and willing to take risks, felt to have greater control, and trusted others more than non-leaders. Moreover, personality changed in emergent leaders: While approaching a leadership position, leaders-to-be (especially men) became gradually more extraverted, open, and willing to take risks and felt to have more control over their life. After becoming a leader, they became less extraverted, less willing to take risks, and less conscientious but gained self-esteem.

CONCLUSIONS

Our findings suggest that people are not simply "born to be leaders" but that their personalities change considerably in preparation for a leadership role and due to leadership experience. Some changes are transient, but others last for a long time.

Personality growth after relationship losses: Changes of perceived control in the years around separation, divorce, and the death of a partner

Background

Previous research suggests that romantic relationships play a crucial role for perceived control. However, we know surprisingly little about changes in perceived control before and after the end of romantic relationships.

Methods

Based on data from the Socio-Economic Panel Study (SOEP), a nationally representative household panel study from Germany, we examined changes of perceived control in the years around separation from a partner (N = 1,235), divorce (N = 423), and the death of a partner (N = 437).

Results

Multilevel analyses revealed that external control beliefs were higher in but not beyond the first year after separation from a partner. Internal and total control beliefs increased gradually in the years after separation. Moreover, internal control beliefs were higher in and especially beyond the first year after the death of a partner compared to the years before. No evidence was found that perceived control already changed in the years before relationship losses or in the years around a divorce.

Conclusion

Taken together, these findings point toward stress-related growth of perceived control after some relationship losses–especially separation and the death of a partner.

Dramatic effects but fast adaptation: Changes in life satisfaction and different facets of affective well-being around the death of a partner and death of a child

Although everyone would agree that bereavement is extremely stressful, surprisingly little is known about changes in different facets of affective well-being in the years surrounding the death of a loved one. On the basis of the Socio-Economic Panel Study, we examined changes in cognitive well-being (life satisfaction) and different facets of affective well-being (happiness, sadness, anxiety, and anger) in the years around the death of a partner (N = 989) and child (N = 276). Data on the death of a partner and child as well as cognitive and affective well-being were assessed yearly since 2007. Multilevel analyses revealed that both events were associated with very large well-being impairments (>1 SD) that were most pronounced for sadness, happiness, and life satisfaction in the first year of bereavement. Afterwards, bereaved individuals managed to recover impressively well: Levels of life satisfaction, happiness, and sadness were on average similar 5 years after losing a partner or child compared with 5 years before the respective loss. Our findings suggest (a) that many individuals tend to be capable to even cope with highly stressful loss experiences and (b) that Set-Point Theory not only applies to life satisfaction but also different facets of affective well-being around the death of a loved one.

Facet-level changes in mothers’ neuroticism and extraversion from early pregnancy to 6 months post-partum

Becoming a parent could be expected to affect personality development, but the existing results on parenthood-personality change connection are mixed. The present study investigated 2445 primi- and multiparous mothers’ facet- and domain-level changes in Neuroticism and Extraversion from early pregnancy to 6 months post-partum, using latent difference score models. The results showed that Excitability and the affective facets of Neuroticism decreased, and the Neuroticism facets Impulsivity and Self-Consciousness increased during the follow-up. Furthermore, mother-perceived child difficult temperament attenuated desirable personality change and amplified the increases in Impulsivity. The results suggested that considering facet-level changes in personality development across significant life events is informative, and that mother-perceived child temperament may represent an important moderator of short-term personality change across the transition to parenthood.

Physical and mental health changes in the five years before and five years after childbirth: A population-based panel study in first-time mothers and fathers from Germany

BACKGROUND

The transition to parenthood is characterized by far-reaching changes in life. However, little prospective-longitudinal evidence from general population samples exists on changes of general physical and mental health in the years around the birth of a child among mothers and fathers.

METHODS

Using data from the German Socio-Economic Panel Study (SOEP), this study examined continuous and discontinuous short- and long-term changes of general physical and mental health from five years before until five years after the birth of the first child in women (N = 1,912) and men (N = 1,742). Whether a child was born was assessed annually throughout the study. Physical and mental health was assessed biannually from 2002 to 2018 with the SF-12v2.

RESULTS

Multilevel analyses revealed that women experienced a considerable decrease of physical health during pregnancy, which remitted after delivery. On average, women's mental health increased in the last year before and first year after delivery. These mental health improvements were stronger in older vs. younger mothers and remained largely stable in the years after childbirth. In contrast, little evidence for changes of general physical or mental health in (expectant) fathers was found.

LIMITATIONS

Physical and mental health was assessed with a short questionnaire only (SF-12v2).

CONCLUSIONS

On average, women's mental health tends to improve before and after the birth of the first child. Men seem to be much less affected by the birth of a child than many previous studies suggest.

Personality maturation and personality relaxation: Differences of the Big Five personality traits in the years around the beginning and ending of working life

OBJECTIVE

At work, people are confronted with clear behavioral expectations. In line with the Social Investment Principle, the beginning and ending of working life might thus promote changes in personality traits that are relevant at work (e.g., Conscientiousness).

METHOD

Based on the data from the Socio-Economic Panel Study (SOEP), we examined nuanced differences of the Big Five personality traits in the years around the beginning and ending of working life. Whether participants had started working or retired in the past year was assessed yearly. The Big Five personality traits were assessed in four waves between 2005 and 2017.

RESULTS

In people who started working, multilevel analyses revealed that Conscientiousness was higher in the first year of working life versus all other years. Extraversion was higher in and after the first year of working life versus before, and Agreeableness increased gradually in the three years after people had started working. In people who retired, Conscientiousness was lower in and after the first year of retirement versus before. No other traits differed around the start of retirement.

CONCLUSIONS

Our findings suggest that the start of working life might promote personality maturation and that retirement might promote personality "relaxation."

Personality and Peripartum Changes in Perceived Social Support: Findings From Two Prospective-Longitudinal Studies in (Expectant) Mothers and Fathers

OBJECTIVE

The aim of this study was to examine changes in perceived social support from early pregnancy to 2 years postpartum and to test whether these changes (a) differ between mothers and fathers or (b) vary as a function of the Big Five personality traits.

BACKGROUND

Higher peripartum social support in (expectant) mothers and fathers has been associated with fewer complications during pregnancy and delivery as well as better parental and offspring health.

METHODS

Prospective-longitudinal data from two regional-epidemiological samples from Germany were used: MARI (N = 396, including n = 293 mothers and n = 103 fathers) and DREAM (N = 2,819, including n = 1,689 mothers and n = 1,130 fathers). The Big Five personality traits were assessed during pregnancy in MARI as well as 8 weeks after the anticipated birth date in DREAM with short forms of the Big Five Inventory. Perceived social support was assessed during pregnancy, 4 months postpartum, and 16 months postpartum in MARI as well as during pregnancy, 14 months postpartum, and 2 years postpartum in DREAM using the short version of the Social Support Questionnaire.

RESULTS

Multilevel analyses revealed that perceived social support decreased across the peripartum period, and this decrease did not differ between mothers and fathers. More extraverted, emotionally stable, agreeable, conscientious, and open parents perceived higher levels of social support across the peripartum period. The peripartum decrease of perceived social support was smaller in parents who were more extraverted.

CONCLUSION

Our findings suggest that especially extraversion plays an important role for high and stable levels of perceived social support across the peripartum period.

IMPLICATIONS

Particularly highly introverted parents might profit from targeted social support interventions.
